Australia’s first biosolids gasification facility

Logan Water has pioneered Australia's first biosolids gasification facility at the Loganholme Wastewater Treatment Plant (WWTP). This facility handles over 90 percent of Logan City’s wastewater and turns human waste into heat energy, reducing the amount of biosolids by 90 percent.

Biosolids gasification involves dewatering, drying, and heating biosolids (treated human waste) at very high temperatures with limited oxygen. The facility captures and reuses its own heat energy to dry the biosolids, while a 1.1MW solar farm with 3,000 panels offsets the facility's electrical energy needs. This process turns biosolids into renewable energy and a sustainable product called biochar. Biochar is a pelletised, sterile, and odourless charcoal product containing nutrients like nitrogen, phosphorus, and potassium. It can be used for:

• soil improvement
• chemical filtering from liquids or gases,
• adding to building materials to sequester carbon and improve strength.

The facility is regulated by an Environmental Authority from the Department of Environment, Tourism, Science and Innovation (DETSI) and the End of Waste (EoW) Code for Biosolids. Logan Water is also helping develop a new EoW Code for Biochar.

Cedar Grove Environmental Centre

This award-winning centre is open daily from 5:30am to 6:30pm. Please note that the gates to the centre and carpark close at 6:30pm, please make sure you leave the Centre before this time.

Community members can visit the site to enjoy:

• a 2.5 kilometer walking track along the Logan River
• shaded seating and picnic tables
• parking, accessible toilets and drinking fountain
• viewing the Cedar Grove Landcare nursery and training facility.

Access is from Cedar Grove Road, and there is a public carpark at the end of the access road. Dogs on a leash are allowed but there is no access for motorbikes, horses, fishing or camping.

Apart from community facilities, the centre is home to Queensland’s first wastewater treatment plant to benefit the environment by producing record low nutrient levels in effluent and offsetting remaining nutrients through catchment restoration. Phase two of the wetlands at Cedar Grove Environmental Centre is expected to commence construction during 2025. Visits to the treatment plant are by arrangement only. The site master plan was developed with a Community Reference Group. Minutes of the meetings of this group are available from Logan Water on request.

Chambers Flat wastewater treatment plant

A new wastewater treatment facility is needed to service development in the Park Ridge, Logan Village and Yarrabilba areas in the coming years.

The planned facility currently known as the Chambers Flat wastewater treatment plant (WWTP) will ultimately be constructed on part of a 144 hectare site at Pleasant View Road, Chambers Flat.

Current status

Logan Water continues to progress planning for a future wastewater treatment plant (WWTP) at the Chambers Flat site. Construction of the WWTP is not expected to commence until after 2032.

Community Reference Group

Council has established the Chambers Flat Community Reference Group (currently on hold).

The purpose of the Community Reference Group is to:

• enhance communication between Council and community members affected by the project
• increase our understanding of community feedback about the development of the Chambers Flat WWTP and connecting trunk infrastructure
• maximise opportunities for the community and environment as part of the project.

Planned wastewater infrastructure – Park Ridge to Chambers Flat wastewater pipeline

Logan Water is currently in the planning phase for new wastewater infrastructure to support the future wastewater treatment plant proposed at Chambers Flat.

Logan Water is proposing to undertake site investigation activities and preliminary design for a new pipeline required to transport wastewater from Park Ridge developments to Chambers Flat. The pipeline is expected to be required in the next five to 10 years.

Loganholme Wastewater Treatment Plant upgrade

Built in 1983, the Loganholme Wastewater Treatment Plant is the largest in Logan City and the third largest in South-East Queensland, processing over 90 percent of Logan City’s wastewater. It Is also the home to the Australian first gasification facility.

Currently, the Loganholme WWTP is undergoing significant upgrades, including the enhancement of the administration building and the addition of a new depot. These improvements aim to boost efficiency and operations, facilitate the relocation from the Smith Road depot, and create a more fit-for-purpose centralized hub.

Travis Road trunk water main project

The project involves construction of approximately 7.2 kilometres of trunk water pipeline and associated infrastructure. The pipeline will be installed using a combination of open trench and underground drilling construction methods.

Where is it happening?

Construction of the new pipeline will occur between Travis Road water reservoir in Logan Village and the Seqwater water pump station in Chambers Flat via Bobermien Road, Stockleigh Road (section complete), Yore Road, Carabeen Road, Geoff Philp Drive and under the Logan River. The works will occur on Council-owned land and infrastructure easements.

When is it happening?

Construction is underway on the horizontal drilling component of the project currently. Open trench works between Lady Ardeen Drive and Yore Road have also commenced with an expected completion in approximately four months (weather and construction conditions permitting).

What can I expect?

Logan Water will make every effort to minimise disruption to the community during these works. However, some localised construction impacts may be experienced at times including:

• Increased levels of noise, dust and vibration. The site team will implement measures to reduce these impacts as much as practical.
• Temporary driveway access restrictions at times. Logan Water will liaise with affected residents in advance of works.
• Changed traffic conditions including temporary road / lane closure(s), reduced speed limits and footpath closures.
• Frequent truck movements to and from work sites to allow machinery / materials to be delivered and removed.
• Some vegetation removal including trimming of overhanging branches. Logan Water will undertake all vegetation removal in accordance with Council and State Government requirements.
